When it comes to your financial health, your credit score is one of those things that'll just keep seeking you out. It's tempting to think that your credit score or credit health will only come into play when you're looking for a mortgage or a new credit card. The truth is that your credit information can be checked far more often than you might think.
The idea of "gaming" your already-excellent credit score to drive it up is not going to benefit you in any substantive way -- there's little or no difference between the interest rates or credit terms offered to people with an 800 and those offered to people with the elusive 850. So gaming it doesn't help anything but your ego.
